Seat support for a motor vehicle

Abstract

A motor vehicle seat support includes a carrier frame on which front forks and rear forks are designed to work respectively with fastening rods that are integral with the floor of the vehicle. Each one of the front and rear forks carries a mobile catch to lock each one of the forks with the corresponding rod, and a device for operating the catches to bring the latter into an unlocked position, so as to make possible the disengagement of the fork in relation to the fastening rods. The front and rear forks are carried by two lower guide rails in contact with upper guide rails braced by a base for holding a seat.

What is claimed as new and desired to be secured by Letters Patent of the United States is: 
     
       1. A motor vehicle seat support comprising: front forks and rear forks which respectively cooperate with first fastening rods and second fastening rods, the first and second fastening rods being integral with a floor of a vehicle, each one of said front forks and rear forks comprising a mobile catch for locking each one of said front forks and rear forks to a corresponding one of said first and second fastening rods;   means for operating said catches to bring said catches into an unlocked position so as to permit a disengagement of said front forks and rear forks from said first and second fastening rods;   first and second lower guide rails which carry said front and rear forks;   first and second mobile upper guide rails in contact with said first and second lower guide rails, said first and second mobile upper guide rails being braced by a base for holding a seat and having first and second raised lateral edges;   front and rear secondary fastening supports incorporated into said lateral edges; and   notches on said secondary fastening supports which are transversely aligned, said notches comprising an opening for permitting an insertion of longitudinally offset crossbars on said seat.   
     
     
       2. A support according to claim 1, wherein a first set of said secondary fastening supports are transversely aligned and limited by a guide ramp directed toward rocking catches for closing the transversely aligned notches on a second set of said secondary fastening supports which are transversely aligned. 
     
     
       3. A support according to claim 2, further comprising a first rocking lever for coupling and for operating said catches for locking said front forks, a second rocking lever for operating and for unlocking said first and second mobile upper guide rails in relation to said first and second lower rails, and a third rocking lever for coupling and for operating said rocking catches for closing said notches carried by said second set-of said secondary fastening supports.
